An object of mass 4.0 kg starts at rest from the top of a rough inclined plane of height 10 m as shown in the figure.
 
  If the speed of the object at the bottom of the inclined plane is 10 m/s, how much work does friction do on this object as it slides down the incline?
 
  What will be an ideal response?

Question 2

In the figure, a block of mass m is moving along the horizontal frictionless surface with a speed of 5.70 m/s.
 
  If the slope is 11.0 and the coefficient of kinetic friction between the block and the incline is 0.260, how far does the block travel up the incline?
 
  What will be an ideal response?

It is believed that the Incas used anesthesia. Evidence supports the theory that shamans chewed cocoa leaves and drilled holes into the heads of patients (letting evil spirits escape), spitting into the wounds they made.
